Adds a GUI to display information about your LTN network.

LTN Tracker displays:

• Depot stops, their current status and assigned trains.
• Stations with provided/requested items, current deliveries and their control signals. Clicking a station name will open the station UI and zoom your view to the station. If you use LTN Combinator, an additional icon allows you to open the LTN-C UI from anywhere on the map and change station settings.
• The combined inventory of all stations, with detailed information for each item.
• A history of recent deliveries.
• Alerts for trains being loaded or unloaded incorrectly and timed out deliveries.

The GUI can be switched on and off using a toggle button in the top left corner or a configurable hotkey. The toggle button lights up in red whenever a new alert is detected.

Special thanks to Optera for creating LTN and for his continued support during the development of this mod.
